Evaluation of Spatial and Temporal Variability of the several datasets for precipitation over Iranian watersheds

Maryam Rostami; Ali Salajegheh; Forood Sharifi; Arash Malekian; TAYYEBEH MESBAHZADEH

Volume 75, Issue 2 , September 2022, , Pages 181-196


  AbstractPrecipitation plays an important role in climatic, water, energy and biogeochemical cycles. Several global and regional data sets currently provide historical estimates of this variable over Iran, including the MWEP and WFDEI forcing datasets and production of some institutions such as MOHC, ...  Read More

Estimation of Runoff and Sediment Yield Potential Using Rainfall and Hydrological Model in Kozatopraghi Watershed

Abazar Esmaili; Mohammad Golshan

Volume 73, Issue 1 , June 2020, , Pages 19-31


  Watersheds are a vast area with different conditions that simulation and studying the processes of runoff and sediment production in these area are critical for managing and maintaining resources. The Kozatopraghi watershed with an area of 766 km2 is located in the south and upstream of the Garesou basin, ...  Read More

Assessing the efficiency of SWAT model for runoff simulation in Gamasiyab basin

Shahab oddin Zarezade Mehrizi; Asadollah Khoorani; Javad Bazrafshan; Ommolbanin Bazrafshan

Volume 70, Issue 4 , January 2018, , Pages 881-893


  Gamasiab River is one of the five main branches of the Karkheh River and plays a basic role in preserving the life and ecosystem of the region. The first step in the adoption of proper and sustainable methods for managing the water resources of the Gamasiyab river is to gain continuous knowledge of the ...  Read More

Comparison of two rainfall – runoff models for simulation of stream flow (Case study: Doiraj river basin in Ilam province, Iran)

heydar ebrahimi; Alireza Moghaddam Nia; Haji Karimi

Volume 69, Issue 3 , December 2016, , Pages 529-541


  The runoff simulation in a watershed provides insight on the processes affecting runoff generation and the stream flow characteristics like spatial and temporal variability of stream flow. This insight helps managers and planners in informed decision-makings on water resources management and planning. ...  Read More

Mapping soil surface salinity using Landsat Data ( Case Study: Bueinzahra


Volume 67, Issue 4 , May 2015, , Pages 631-640


  This research was done in order to submit a model for salinity map made with TM satellite data and salinity values in a Buienzahra. The necessary processings such as principal component analysis and producing of different indices was done on the main bands. The 38 soil samples using random sampling (with ...  Read More

Comparing the Accuracy of Soil Map Prepared by Geopedology and Usual Method of Iran (Case Study: Kouhin)

Zohreh Alijani; Fereydoun Sarmadian; Seyed Rouhollah Mousavi

Volume 67, Issue 1 , May 2014, , Pages 93-102


  Today, extensive improvements in fields of soil mapping have increased the purity and accuracy ofsoil maps. Usual mapping methods moreover depend on skills and experience of surveyor inidentifying and delineating the boundaries, also need the high cost and time consuming that face thesoil mapping with ...  Read More

Simulating discharge and sediment production using SWAT in Chehelchai Watershed of Golestan Province

Akram Arefi Asl; Ali Najafinejad; Farshad Kiani; Abdolrassoul Salmanmahiny

Volume 66, Issue 3 , November 2013, , Pages 433-446


  Runoff and sediment measurement is difficult in mountain watershed because of many different problems such as time and financial limitations. So using simulation model is necessary in this regard. Accuracy and precision evaluation of models for different watershed of Iran is necessary. The aim of this ...  Read More
